Compound eyes a continuous feature of evolutionResearchers from Cologne, Tallinn, and Edinburgh have found out that the compound eyes of today's insects and crustaceans are still constructed in much the same way as 500 million years ago.

How ribosomes shape the proteomeCells are crowded with macromolecules, which limits the diffusion of proteins, especially in prokaryotic cells without active transport in the cytoplasm.

New approach measures early human butchering practicesResearchers, led by a Purdue University anthropology professor, have found that statistical methods and 3-D imaging can be used to accurately measure animal bone cut marks made by prehistoric human butchery, and to help answer pressing questions about human evolution.

Routing gene therapy directly into the brainThe technique, which could be used to transplant donor-matched hematopoietic stem cells (HSCs) or a patient's own genetically-engineered HSCs into the brain, was reported in Science Advances today by researchers from the Dana-Farber/Boston Children's Cancer and Blood Disorders Center and the San Raffaele Telethon Institute for Gene Therapy.

Living on thin air -- microbe mystery solvedUNSW-Sydney led scientists have discovered that microbes in Antarctica have a previously unknown ability to scavenge hydrogen, carbon monoxide and carbon dioxide from the air to stay alive in the extreme conditions.

Psychosis incidence highly variable internationallyRates of psychosis can be close to eight times higher in some regions compared to others, finds a new study led by researchers at UCL, King's College London and the University of Cambridge, and published in JAMA Psychiatry.

Children on sex offender registries at greater risk for suicide attempts, study suggestsA new study led by researchers from the Johns Hopkins Bloomberg School of Public Health found that children who were legally required to register as sex offenders were at greater risk for harm, including suicide attempts and sexual assault, compared to a group of children who engaged in harmful or illegal sexual behavior but who were not required to register.

Go with the flow (or against it)Queen's University researchers are using magnetic fields to influence a specific type of bacteria to swim against strong currents, opening up the potential of using the microscopic organisms for drug delivery in environments with complex microflows- - like the human bloodstream.

Needle in a haystackOvercoming a major hurdle in the field of microbiome research, scientists have developed a method to elucidate cause-effect relationships between gut bacteria and disease.

Spinal tap needle type impacts the risk of complicationsThe study says using atraumatic needles for lumbar punctures is just as effective and results in a significant decrease in complications such as headaches and also more than a 50 percent reduction in patient readmissions and return to emergency rooms for narcotics or blood patches.

What makes a happy working mom?A happy working mom feels competent in interacting with her child, experiences a sense of freedom and choice in her actions, while having a warm and affectionate relationship with her baby.

Probiotic gets a boost from breast milkSupplementation with probiotics can improve a person's gut health, but the benefits are often fleeting, and colonization by the probiotic's good microbes usually doesn't last.

Marine invertebrates have noisy human neighborsMarine invertebrates are impacted by the rising levels of underwater noise produced by humans, but the production of underwater noise is not only difficult to control, but the direct effect on marine invertebrates can be challenging to observe or measure.

NASA's CATS concludes successful mission on space stationA spaceborne lidar instrument that fired more laser pulses than any previous orbiting instrument has ended its operations on the International Space Station, after a successful 33-month mission to measure clouds and tiny atmospheric particles that play key roles in Earth's climate and weather.

Lack of sleep could cause mood disorders in teensChronic sleep deprivation -- which can involve staying up late, and waking up early for work or school -- has become a way of life for both kids and adults, especially with the increasing use of phones and tablets late into the night.

Technology may help increase number of kidneys transplantedMany deceased donor kidneys are declined for transplantation because of concerns over their quality, but a new BJS (British Journal of Surgery) study found that a technique called normothermic machine perfusion can assess the quality of a kidney and determine its suitability for transplantation.

'Green' cataract surgery model drastically reduces environmental footprintFaculty at NYU School of Medicine report that a healthcare center in India's model for cataract surgery emits 96 percent less carbon than in the United Kingdom -- and a likely even greater savings in the United States -- while yielding comparable or better health outcomes for one of the world's most common surgical procedures.

Disorders of the voice can affect a politician's successThe acoustics of political speech are known to be a powerful influencer of voter preferences, but vocal disorders can change the qualities of a person's speech, and voice scientists have found that this alters politicians' perceived charisma.

Freezing trees, finding answersIce storms can wreak havoc on communities. Frozen limbs, dragged down by the weight of the ice, can snap off and fall on cars, homes, and power lines.

Short intervention boosts safe-sex skills in teen girlsA recent study from North Carolina State University and the University of North Carolina at Chapel Hill finds that a 45-minute online sexual health program improved the ability of teen girls to communicate effectively about safe sex.

Forests are the key to fresh waterFreshwater resources are critical to both human civilization and natural ecosystems, but UBC researchers have discovered that changes to ground vegetation can have as much of an impact on global water resources as climate change.

#465 How The Nose KnowsWe've all got a nose but how does it work? Why do we like some smells and not others, and why can we all agree that some smells are good and some smells are bad, while others are dependant on personal or cultural preferences? We speak with Asifa Majid, Professor of Language, Communication and Cultural Cognition at Radboud University, about the intersection of culture, language, and smell. And we level up on our olfactory neuroscience with University of Pennsylvania Professor Jay Gottfried.
